Answer:
12-14 october
Explanation:
The probable period of exposure is calculated as follows:
- Know the range of the incubation period
- Start counting back from the days of the first case by subtracting the first number of incubation period range
- Count back the days from the last case by subtracting the last number of incubation period range.
- This will give a range which will be the period of exposure.
From the question,
- Incubation period range 1-15
- Date of first case = october 15
- Therefore, first date of exposure = 15 -1 = 14
- Date of last case = 22
- Therefore, last date of exposure = 27 - 15 = 12
- Thus, the range is 12-14 october which is the probable period of exposure.
Answer: Excessive movements of the walls of the abdomen
Basically babies belly breathe, that is they undergo abdominal pattern of respiration( instead of the abdomino- thoracic pattern in adult), through their abdomen.
<u>This is because, their thoracic walls are not fully functional to undergo the normal adult mechanisms of breathing</u>.
<u>The ribs are short in length due to incomplete ossification. They curve out wards, at low angle, their sternum, is shaped horizontally.</u>
These features reduce the activities of the inter coastal muscles and the thoracic cage in the mechanism of infants breathing,compare to the long ribs, obliquely shaped rib cage, with lower sternum of adult which permit the abdominal-thoracic breathing pattern.
Therefore ,when the diaphragm distends during breathing ,its movement pushes the organs of the abdomen down; because infants have rapid respiratory rates, the distends created rapid expansion and contraction of the walls of the abdomen to gain enough abdominal pressure.
This together with the movement of organs of the abdomen from the pathways of diaphragm created the excessive movements of the abdominal walls. This rapid abdominal wall movements creates discomfort and distress for the infant during this mechanisms.

Clown fish and sea anemones.
Explanation:
Spillover infection, also known as pathogen spillover and spillover event, occurs when a reservoir population with a high pathogen prevalence comes into contact with a novel host population. The pathogen is transmitted from the reservoir population and may or may not be transmitted within the host population.
The removal of the cell membrane.
The membrane regulates homeostasis by letting "stuff" (general term) in and out of the cell.
